Backends arm: Bump ethos-u/core_platform (#10514)

Bump core_platform to a newer version that includes the patch moving
.rodata into DDR thus making the patch reduntant.

But, lurking inside that patch was a add of .got into DDR section so
that needs its own patch to be handled.

Once the 0001 patch was fixed the 0002 patch needed some updates.
